I Am Not Sure if B is Correct Please Help Me

YZ is the diameter, so arc YZ = 360°/2 = 180°

arc XZ = 360° - arc YZ - arc YWX = 360° - 180° - 100° = 80°

∠XYZ is an inscribed angle <span>so it is equal to half the arc XZ

</span>∠XYZ = 80°/2 = 40°

A function that can be written in the form f(x)=ax2+bx+c, where a, b &amp; c are real numbers and a is not equal to zero.
patriot [66]
Hello there!

I'm not exactly sure of what answer you are looking for, however,
f(x)=ax^2+bx+c represents a quadratic function.

Quadratic functions always have their highest exponent at 2, nothing more and nothing less.

Examples of quadratic functions are...
•x^2
•3x^2
•3x^2+2
•3x^2+2x
•3x^2+2x+1

I really hope this helps!
Best wishes:)
